To all 'wlosilit stay concern:

Beit huovm that 1, Joan W. Srmoxn! Brooklyn, in the State of Key York, have invented s new sud useful Method of Extinguishin Fire in Oil or other inflammable Liqmds; and I do hereby deelare'the following to be a mu and correctdescription of the same, reference being had to the aecompenyingdrawin in whichlure 1 is a vertical section of one form of apparatus ads ed to the application of my invention to t e extinguishing of tire in'au oil-tint.

.' My invention consists in the introduction of carbonic-sold gas beneath the surface of any burning liquid for the purpose of extinguishin; the tire. I

lhiiTellcct either lv =;enerutiug the carbonic-acid gas in the Mime vessel which is employed to hold the inflammable liquid, or

hflcolnlueting the ans in pipes fronuny suitab reservoir placed outside of the containingvessel, and allowing it to escape belovr the our face of the liquid.

The first of these methods is that represented in the accompanying drawing. A marks wrprdinnry oil-tank, such as is eommonlyeuv played at the oil-wells to receive the crude petroleum us it comes from the pumps. In the bottom of this tank is placed a lnyer'oi a, or other suita ble material for the generation of carbonic-acid gas. Water is then introduced to the depth of a few inches above the surface of the marble-dust. The oil contained in the vessel floats upon the surface of the water. A vessel, B, coutaininga suitable acid is connected by a pipe, (3, with the; bottom or lower part of the tank A. The opening of the pipe 0 into the vessel B is controlled by a vnlv ted by a lever, to which the cord is attno hm tter runs'stsndsrd fixed to the sideol the vessel B. and to the upper end otthe valve-rod, es

own. By ulliug the cord, the valve is raised and theucdiu vessel Bpaseesdown peGinto the bottom of tank A, where it poses the carbonate of lime or sodspnd liberates curbonio'neid panwhich, rising through the water and'oil, ex gnishes the tire buruingon the surface of the oil. V 7

Other t'orms of apparatus ms be adopted pith equally good results. I ve eoutem' pitted the use of any of the o'rdinsry generators of carbonic-acid gas, connected with the reservoir of oil, nuphths, or otherintlsmmable liquid, byn pipe entering near the bottom of the reservoir, or bye flexible or other tube having a nozzle introduced in any convenient manner below the surface of the liquid;

What I claim as my invention, and desire to secure by Letters Patent, is-

An apparatus, ve of form, in which ttlihe iutroduef ioiiiI of an: beneath esuri'ueeo o ,petroleununn orother inflammable liquid is employed to eiliectthe moreperi'ect ditl'asiou ci'said gss outhesurface of such liquid, for the purpose oi extinguishing fire burning upon said surfsce, said up tus consisting of any suitable device, oit or for generating carbonic-aid pus beneath the surface of theoil within the oil-tank, or for introducing said g'ssbenesth thesurtsce of the liquid from any convenient placed outside of the oil-.tsnk, all substantially as described.

The above specification of a said invention signed and witnessed at Wuhi ngtonthis 12th day of March,- A. D. 1878.
